BUNG FOR BARRELS.

SPECIFICATION formingpart of Letters Patent No. 270,942, dated January 23, 1883.

Application filed November 18,1882. (No model.)

To all whom it may concern:

Be'it known that we, RICHARD J. FLooD, a

citizen of the United States, and JAMES RICH- ARDSON,a citizen of Great Britain,both resid- 5 ing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Bung for Barrels and we hereby declare that the following is afull, clear, and exactdescription thereof, reference being to had to the accompanying drawings, forming part of this specification, wherein- Figurel representsasolid metallic and righ thanded screw-plug, having a large flat circular head, provided at equidistant points around 1 its rim with three radial notches Fig. 2, a top view of the plug-head. Fig. 3 represents a side elevation of a metallic tube provided with a left-handed exterior screw and a flat circular head, also furnished with three radial notches 20 in the edge of its rim; Fig. 4, a top view of the head of the tube; Fig. 5, an external view of our improved separable bung, consisting of the solid metallic plug fitted and screwed into the hollow of the stout metallic tube; Fig. 6,

2 5 a transverse vertical section of the same. Figs.

7 and 8 simply show the notched and disk-like I top or'head of the solid plug,and are mere repetitions of the view Fig. 2.

Our invention consists of a separable me- 0 tallic bung formed in two parts, one of which is a short stout tube, a, provided exteriorly with a left-handed screw, 1), and at one end with a flat circular projecting flange, 0, having in its edge, at equidistant points, three radial 3 5 square notches, d d d, by which said tube may -be caught and tightly screwed into a barrel.

The interior of this tube a is formed with a right-hand screw, f, and into this a solid me tallic plug, 6, provided with a correspondingly- 0 shaped-screw, g, is made to fit. lhis plug is also provided with a circular flange or flat pro- Ijecting head, h, in the edge of which are cut or otherwise formed three radial notches, 'i t i, answering in shape and size to those in the flange of the tube a, just described. This tubular portion a of the bung is intended to be screwed permanently in a stave or head of a barrel, and used in connection with the solid plug 6, in such amanner as that the tube may be securely closed when the barrel is full, or slightly opened by a partial turn of the plug to admit air in such quantities as will allow the contents of the barrel to be drawn off through a spigot, if desired; or the projecting flange of the plug may be so snugly screwed down upon that of the tube as to practically make thejoint existing between them air and water tight; .or the plug may be readily unscrewed and removed from the tube through which the barrel may be filled,or for other purposes.

Having described our improved metallic bung, we claim A separable metallic bung formed in two parts, one of which consists of a short stout tube, a, provided interiorly with a right-hand screw, f, and exteriorly with a left-hand screw, b, and atone end with a flat circular projecting flange, 0, having in its edge, at equidistant points, three radial square notches, in combination with a solid metallic plug, 6, provided with an external screw, g, corresponding to that in the tube a, and with aflatcircular projecting flange, h, having in its edge three radial square notches, arranged at equidistant points, 75 as shown and set forth.
